Thin film transistor and method of making the same.

摘要

A source electrode (12) and a drain electrode (13) are formed apart on an insulating substrate (11), and a semiconductor layer (14) is formed on the szbstrate (11) between the source and drain electrodes (12, 13). An insulating organic molecular film (21) is formed all over the source and drain electrodes (12, 13) and the semiconductor layer (14). Ions are implanted into a selected top surface region of the insulating oganic molecular film (21) corresponding to the semiconductor layer (14), by which chains of molecules in the surface region to form free carbon, providing a conductive gate electrode (22) and the remaining part of the insulating organic molecular film (21) forming a gate insulating film (23).
